Application filed November 1 1919.. Serial No. 335,024.

To all whom it 'may concern:

Be it lrnown that l, Chances E. Johnson, a subject oi the King oil.tGreat Britain, rcsiding at Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented new and useful linprovements inHeat Concentrating` and Deilecting llevices7 of which the following is aspeciiication.

The invention relates to stoves and ranges and has for an object toprovide a d evice 'for use in connection with a stove or range, forconcentrating the heat beneath a particular lid or vessela or detiectingthe heat from a point beneath the device to an adjacent pot or vessel.receiving opening` ot the stove My device is particularly adapted foruse in connection with domestic stoves and ranges and particularly inkitchen stovesj whether they be or coal stoves and to this end l providea simple device which is arranged to depend in one et' the openings inthe stove top and has suitable means for brinpgingr about concentrationof the heat beneath the particular opening; in which it is placed or'i'or deflectinp; the heat to an -adiaeent opening; in the stove top.

ln the further disclosure oli the invention7 reference is to be had tothe accornpanying` drawings constitutingn a part of this speciiicationin which similar characters ot relierence denote corresponding parts inall the views, and in which,-

Figure l-is a perspective view of the device by itself.

Fig. 2-is a vertical sectional view taken through the device showing thearrangenient of one of the pintles Fig. 3is a side elevation ot theoperatingr member or key, and

Fig. l--is a plan view of a stove top showing the opening with one of mydevices positioned to show the manner of guiding or defiecting the heatto the openings.

Referringl more particularly to the views I provide a substantiallycircular body 10 formed to provide an upper horizontal circular rim 11and a substantially semi-circular dependingwall 12, which is so disposedas to the riin 1L to provide an annular flange 13 formed by theperiphery of the rim 11 and which may be also termed the outer edge ofthe rim, whereas the inner edge oi the rim forming an opening 1e has aprojecting ledge 15 Jlor a purpose which will be hereinafter moreclearly described. The semicircular Wall 12 has each end cut away as at16 and is formed with a longitudinally apertured circular bearing` heador hinge element 17. Between the ends of the wall 12 there depends fromthe underside of the rim 11, support'18 which also forms a Wall andwhich is provided with opposed cut away portions 19 and projectinglongitudinal apertured circular bearing' heads or hinges 20. With thisintermediate support 18 it will be seen that a plurality of ad gacentpassages 21 are provided and these are normally closed by doors orswinging members 22, each consisting of a slightly curved plate 23formed with a longitudinally apertured circular hinge element 24C. Apair ot the doors 22 are provided for each passage 21 and one of thedoors in each pair is hinged to one of the hinge elements 2O by havingits hinge element 24 projectino into the cut portion 19 with a suitableoperating` pin 25 in the nature of a pintle provided to swinginglysupport the door in position5 the other door being of course mountedupon one oi the hinge elements 17 and having' its hinge element 2%extending into the cut away portion 16. onel of the operating pins orpintles 25 being' employed for the hingring or' each door. Each door hasa squared depression 26 in the upper end of the binde element 2ithereor" and the body 10 in the rim 11 is provided with openings 27registeringr with the depressions 26 so thai a lfev 28. including asquared end 29 and handle 30. can be ar ranged to have its squared end29 pass through one ot' the openings 27 and extend into the squareddepression adjacent the opening' so that a swinging movement can beimparted to the door or doors t0 open or close the same.

A stove top is indicated by the numeral 31 and is provided with openings32 which are bordered by flanges 33 formino' seats so that when one ofthe devices described is disposed in one oi the openings, the flanges 13will rest upon the seat 83, thus positioning the device in the openinglof the stove top. A suitable lid for the circular body 10 can beprovided, the lid being indicated by the numeral 34, and when inposition is adapted to close the opening 14, resting upon the ledge 15'.lt will be seen, by reference to the views that each door has a stop lug35 formed with its hinge element to engage the face of the Wall 12 orsupport 18, as the case may be, to limit the opening` inoveinents Y ofthe doors.

Now it will berseen that when all ofthe doors are closed that the walll2 which normally is semi-circular, will through the Y medium of theclosed doors and the interposed support 18 form a continuous circularWall which, depending' beneath the stove top andclose to the source ofheat, will tend to confine the heat beneath the lid or cooking vesselwhich may be placed upon the body 10, or upon the stove top over theopening 14. When it isdesired to deflect a portion of the heat to theadjacent opening of the stove top, and which may or may not be providedwith one of the devices, it is only necessary to swing certain or all othe doors into positions whereby the passages 2l. will beV openedsofthat the heat which rises within the wall l2 will be deflected by thesuperpos'ed cooking vessel or lid and passing through the open passageor passages,'vvill be guided toward the adjacent opening, over which acooking;r vessel has been disposed,

containing probably a food which is to be subjected to a slightl/ieatingiV action to bring about a simmering of the'contents of thisvessel.

Y lt will of course be understood that the device described can be usedin connection with various forms of stoves and ranges and Lseesoe can beoperated as desired to deflect or guide Y the heatfroni one openingtoward the other or concentrate the heat beneath one ofthe openings overwhich a lid or cooking vessel has been placed and althoughl have shown aparticular Jorrn of niy invention in the movement,saidY annulus having*openings therein arranged above the pivot end of said swinging sections,said pivot ends being; pro-- vided with squared recesses and adapted toreceive a tool for rnovingthe sections to open and closed positions,said sections normally forming a continuation of the said wall and theinner periphery of said annulus being; odset to provide a ledge disposedwithin the eoniincs of the said annular wall for the purpose specii'ied.1
